"Within the NASA database application, for example, 67 percent of the failures were triggered by only a single parameter value, 93 percent by two-way combinations, and 98 percent by three-way combinations. The detection-rate curves for the other applicati

While the most basic form of combinatorial testing, pairwise, is well established, and adoption by software testing practitioners continues
to increase, industry usage of these methods remains patchy at best. However, the additional training required is

With the NASA application, for example, 67% of the failures were triggered by only a single parameter value, 93% by 2-way combinations, and 98% by 3-way combinations. The detection rate
curves for the other applications studied are similar, reaching 100% detection with 4 to 6 way interactions."
